Formic Acid Challenges
Formic acid is a chemically aggressive substance. Considering the nature of the substance, we had to check the compatibility of construction materials, and also any seals. The most suitable material for the task was 316 stainless steel. 316 Stainless steel has excellent chemical compatibility, corrosion resistance, but is particularly effective in protecting against corrosion in acidic environments.
Bell Flow quoted three products to fit the brief accordingly – a Blancett B1100 turbine and solenoid valve, both in stainless steel. And finally, a Fluidwell F130 batch controller, with mechanical relay output to complete the set up.
This allows the customer to enter the volume required into the batch controller. The flow is subsequently measured accurately by the flow meter. Pulses are then sent to the batch controller, which in turn closes the valve at a set value. Allowing for controlled, precision batch measurements.
This system ensures accurate batch control for formic acid. Ultimately producing an end product of consistent quality specifications.
